I have been meaning to document this for ages. I often find myself supporting clients who are located on the other side of a horribly slow WAN / VPN / 2 Cans and a piece of string link. Slow as in even Navisphere Express times out in the web browser. That’s when a ninja-admin such as myself whips out his command-line fu. All commands below are to be entered on a single line and substitute %username% and %password%

There has been a lot of movement in the virtualization space recently, what with the release of vSphere 5 and Microsoft giving us a sneak peek at the upcoming Hyper-V 3.0. All in all it seems that Hyper-V is a very rapidly maturing product, and Microsoft is adding the features and scalability so craved by enterprises. Indeed, it also appears that they are pulling ahead of vSphere in certain areas.

The table below highlights some key performance maximums

vSphere 5

In addition to that Hyper-V 3.0 will also bring the following to the table:

Live storage migration

This allows you to move you VHDs to another volume whilst the VM is online. The volume need not reside on shared storage

About Me

About This Blog

This blog serves 2 purposes. Firstly, I want to share information with other IT pros about the technologies we work with and how to solve problems we often face. I work with technologies from the desktop to the data center, Active Directory, System Center, Exchange, Hyper-V, VMware, Networking and Storage.

Less altruistically, I use my blog as a reference. There's so much to learn and remember in our field that it's impossible to keep up. By blogging, I have a notebook that I can access from anywhere. It has made me look much smarter than I probably am on many occasions.
